“…Some investigators have found no association, 23 whereas others have. 24 In our study, emergency CS in particular emerged as a risk factor of atopic dermatitis in the PT group, supporting the role of mediators other than the effect on the microbiota between CS and the occurrence of atopic dermatitis. The smaller number of infants in the PT group may account for some differences between this group and others.…”

“…A series factors including age, residence status, exposed to passive smoking, premature birth, breast-feeding, pet ownership, delivery pattern and choosy in food were previously considered to be associated with AD prevalence and evaluated in multiple studies 19 20 21 22 23 24 25 26 27 28 29 . AD prevalence is generally considered declined with age and to be lowered in rural areas, which is consistent with current study.…”

Prevalence of atopic dermatitis (AD) is increasing worldwide. Up to date, there has been no face-to-face nation-wide study in China. We aim to explore the prevalence of clinical diagnosed AD in children aged 1–7 ys in China. Twelve metropolises were chosen from different areas of China. In each region, we selected 4–10 kindergartens and 2–5 vaccination clinics randomly. A complete history-taking and skin examination were performed by dermatologists. The definite diagnosis of AD and the severity were determined by two or three dermatologists. All criteria concerned in UK diagnosis criteria, characteristic presentation of AD and atypical manifestations were recorded in detail. A total of 13998 children from 84 kindergartens and 40 vaccination clinics were included. The prevalence of AD was 12.94% by clinical diagnosis of dermatologists overall, with 74.6% of mild AD. Comparatively, prevalence of AD based on UK diagnostic criteria was 4.76%. This is the first face-to-face nation-wide study in Chinese children aged 1–7 ys, revealing that the prevalence of AD in children is closer to that of wealthier nations.

“…An Osaka Maternal and Child Health Study investigated the relationships between breastfeeding and atopic eczema in Japan, and found that exclusive breastfeeding for more than 4 months (OR 2.41, 95% CI 1.10-5.55) or partial breastfeeding for more than 6 months (OR 3.39, 95% CI 1.20-12.36) significantly increased the risk for the development of atopic eczema in children of parents without allergic history [27]. Yu and coworkers [28] studied the relationships between C/S and AD and found a significant higher risk of AD for those children born by C/S (OR=1.50, 95% CI =1.01-2.22). These results corresponded to our study, indicating breastfeeding and C/S increased the risk for the development of AD in children from non-atopic parents, while these two factors were not significantly associated with development of AD in children with atopic parents.…”

Background: Allergic diseases are thought to be inherited. Prevalence of allergic diseases has, however, increased dramatically in last decades, suggesting environmental causes for the development of allergic diseases.Objective: We studied risk factors associated with the development of atopic dermatitis (AD), allergic rhinitis (AR) and asthma (AS) in children of non-atopic parents in a subtropical country.Methods: In a birth cohort of 1,497 newborns, parents were prenatally enrolled and validated for allergic diseases by questionnaire, physician-verified and total or specific Immunoglobulin E (IgE) levels; 1,236 and 756 children, respectively, completed their 3-year and 6-year follow-up. Clinical examination, questionnaire, and blood samples for total and specific IgE of the children were collected at each follow-up visit.Results: Prevalence of AD, AR and AS was, respectively, 8.2%, 30.8% and 12.4% in children of non-atopic parents. Prevalence of AR (p<.001) and AS (p=.018) was significantly higher in children of parents who were both atopic. A combination of Cesarean section (C/S) and breastfeeding for more than 1 month showed the highest risk for AD (OR=3.111, p=.006). Infants living in homes with curtains and no air filters had the highest risk for AR (OR=2.647, p<.001), and male infants of non-atopic parents living in homes without air filters had the highest risk for AS (OR=1.930, p=.039).Conclusions: Breastfeeding and C/S affect development of AD. Gender, use of curtains and/or air filters affect AR and AS, suggesting that control of the perinatal environment is necessary for the prevention of atopic diseases in children of non-atopic parents.

Atopic dermatitis is associated with Caesarean sections in Korean adolescents, but asthma is not

Abstract: Atopic dermatitis in adolescents was associated with Caesarean delivery, which is common in South Korea. The findings suggest that the frequency of this practice should be reconsidered and that further research with longitudinal evaluation of relevant mechanisms is needed.
